' RUBBER HEEL.

Speciilcation of Letters Iatent. Patented Nov. 12, 1912.

Application filed April 22, 1912 Serial No. 692,223.

' tion is to provide a rubber heel for boots and shoes, which can be applied to and removed from the shoe more easily than is possible with rubber heels now m use, and

which can be held upon the shoe Without the use of nails.

'In the drawings Figure 1 is a side elevation and Fig. 2 is a rear elevation of a shoe to which the rubber heel is applied; Fig. 3

' is a bottom plan view of the device or devices secured to the bottom lift of the leather part ofihe heel; Fig. 4 is a top plan or perspective yiew of the rubber part of the heel; and Fig. 5 is a perspective view of part of the locking means.

The heel is composed of a suitable number of hits 1 which may be made of leather, wood, or other suitable material. To the bottomlift the members 2 are secured, each of said members being preferably an iron piece which is shaped like a wedge or truncated prism, and both of the members 2 being disposed so that their inner edges 3 are parallel and substantiallv perpendicular to the'breast of the heel. Between said members 2 and thebottom lift 5 is a thin metal plate (5. Screws 7, the heads of which are countersunlzlat 8 in the members 2, pass through said members 2 and through plate (3 and into the leather lifts 1.

The rubber cushion 9 is provided on its upper surface with recesses 10 into which a metallic plate 11 tits. The plate 11 and the recesses 10 are shapedso as to conform to the shape of the members 2 so that, when the heel is afiixed to the shoe, the members 2 will exactly till the spaces 10.

The spring-like tongue is riveted at 13to the plate (3 so that said tongue is permitted to project downwardly from the leather part of the heel. The plate 11 is punched or perforated at 14, and when the heel is assembled the spring-like tongue seats within said notch or perforation 14 and locks the rubber cushion in place upon the shoe.

In order to permit the removal of the'rubber cushion from the shoe, as is necessary when the cushion becomes worn or misshapen, the cushion is perforated at 15 and anawl or similar tool can be driven through the perforation 15 until it strikes the tongue 12. The tongue can thus be pushed up and out ofthe notch 14, after which the rubber cushion can easily be removed.

lVhen the device is to be assembled the cushion is forced toward the left in Fig. 1, the members 2 fittin within recesses 10 and pushed toward the off in said Fig. 1 until the tongue 12 seats within the notch 14. This will lock the rubber cushion 9 upon the heel and the cushion will there remain'until the ton ue is forced out of said notch. When t at is done the cushion may be pulled toward the right in Fig. 1 and thus removed from the heel. f

Obviously many changes in details of construction may be made without departing from the scope of the invention.

\Ve claim as our invention:

A heel comprising a resilient cushion, the upper surface of which is provided with a pair of substantially parallel wedge-shaped recesses, a metallic plate of such shape as to cover the exposed surface of said, recesses and the rib thcrebetween, a ipair of strips upon the bottom of the heel corresponding in size and shape to said recesses and adapted to be received therewithin, and :1V tongue upon the heel located in the space between said strips and )rojecting downwardly from said heel, said late being provided with a. perforation and the upper surface of said cushion beiu provided with a notch within which said fongue'is received.

In testimony whereof we have hereunto ailixcd our names in the presence of two witnesses.
